Definitions

  • the present invention relates to a system for assembling, in a plurality of adjustable positions, two components of a prosthesis.
  • GB-A-2 141 345 describes an adjustable connecting device for joining two parts of a prosthesis, this device comprising a first and a second connecting element intended to be fixed each on the parts of the prosthesis to join together, the connecting elements being in mutual contact or with an intermediate connecting member by flat or spherical parts directly resting against each other and capable of being displaced with respect to each other by sliding or pivoting, screws being provided to lock them in position after adjustment.
  • a projecting member integral with part of the prosthesis, is housed in a hollowed-out portion in the form of a bowl of an intermediate connecting member and is supported by a flat part against the bottom of the bowl-shaped part, against which it can thus slide to be brought by translation from the desired position.
  • Screws engaged in threads arranged transversely in the lateral walls of the bowl can bear by a free end against the lateral flanks of the projecting member, inclined relative to the bottom of the bowl, in order to lock this member in position .
  • the present invention aims to remedy this drawback by proposing an assembly system, in a plurality of positions, adjustable in translation, in rotation and angularly, of two constituents of a prosthesis, in which a projecting part integral with the one of these components is, as previously, engaged in a recess forming a bowl of the other constituent of the prosthesis or of an intermediate connecting element (or vice versa), while screws arranged transversely with respect to the side walls of the bowl come into abutment, as in the prior art, against the lateral flanks of the projecting part, but without the bottom of the bowl taking support directly against the facing surface of the projecting part, thereby avoiding the latter from 'be subjected to very significant efforts or couples.
  • the outer edge of the bowl-shaped recess is supported so as to be able to slide in a rectilinear manner in at least one direction on a surface of the constituent of which the projecting part is integral, this part in the projection being further, in any position, spaced from the bottom of the recess forming a bowl.
  • the edge of the bowl may be supported by at least a first flat surface against at least a second flat surface of the element secured to the projecting part and, in such an embodiment of the invention, by relative sliding of the first planar surface against the second planar surface, it is possible to adjust in translation in any direction the position of the two parts of a prosthesis or of a part of a prosthesis and of an intermediate connecting element.
  • the edge of the bowl may also be supported by at least a first cylindrical surface against at least a second cylindrical surface of complementary profile of the element to which the protruding part is secured and, in such an embodiment, the first and the second surface can slide relative to each other in one direction, parallel to the axis of the cylindrical surfaces and rotate relative to each other around the axis of the cylindrical surface, to allow adjustment of their relative positions.
  • the various elements may finally advantageously be adjustable with respect to each other by rotation about an axis perpendicular to the flat sliding surfaces or at the axis of cylindrical sliding surfaces.
  • the protruding parts will have the shape of a pyramid trunk with rectangular base and they will protrude from a cylindrical part to which the part projection will be connected by the small base of the trunk of the pyramid.
  • An embodiment of the invention therefore consists of a modular connection device, adjustable in position, between two components of a prosthesis, this device comprising a first element, capable of being made integral with a first component of the prosthesis , a second element, capable of being made integral with a second component of the prosthesis, and an intermediate element, capable of being made integral, in an adjustable position, respectively, of the first and of the second elements, by cooperation of a part male and / or female part, respectively, of this intermediate element, with a female part and / or a male part of the first and second elements, assembly members such as screws being provided for locking one relative to the other, in a plurality of positions, on the one hand, the first element and the intermediate element, on the other hand, the second element and the intermediate element, this device is so characterized in that each of said male parts comprises a portion in the form of a trunk of pyramid with a rectangular base projecting from a portion of cylindrical shape, to which it is connected by its small base, the axis of the portion cylindrical being substantially parallel to two
  • cylindrical shape includes all the surfaces allowing the female parts and the associated male parts to pivot with respect to each other about a common axis of rotation.
  • the intermediate element of the connection device may comprise two male parts each associated with a female part of the first and second elements of the device.
  • the intermediate element may include two female parts, each associated with a male part of the first and second elements of the connecting device.
  • the intermediate element may comprise a single male part, associated with a female part of one of the first and second elements, and a single female part, associated with a male part of one of the first and second elements of the device.
  • Screws screwed into threaded recesses of the first and second elements of the device and coming in abutment against the sides of the portions in the form of a truncated pyramid, allow, after adjustment of the relative positions of the components of the prosthesis respectively integral with the first and second elements of the device, to lock these elements in their respective positions.
  • FIG. 3 of GB-A-2 141 345 For clarity and to better highlight the advantages of the system according to the invention, these figures can be compared to FIG. 3 of GB-A-2 141 345.
  • the system according to the invention comprises two parts 1 and 2, which can each be integral with a part of a prosthesis or with a connecting element between two parts of a prosthesis, but which can also make integral part of this prosthesis part or of this connecting part.
  • the part 1 comprises a flat plate 3, on the surface of which protrudes a part 4, which here has the form an inverted pyramid trunk, that is to say a pyramid trunk whose largest base is distant from the plate 3, but which could have any other shape.
  • a part 4 which here has the form an inverted pyramid trunk, that is to say a pyramid trunk whose largest base is distant from the plate 3, but which could have any other shape.
  • the part 1 is shown as being in one piece, but the plate 3 and the part 4 could as well be separate and made integral with one another by any means known in the art.
  • Part 2 can have any shape. It comprises a recess forming a bowl 5, the edges of which rest by a flat part against the surface of the plate 3 from which the part 4 protrudes. The latter is engaged in the recess 5 forming a bowl, but without coming into contact with the background thereof, unlike the systems of the prior art.
  • the part 2 does not bear against the projecting part 4, the latter does not support any force and is not likely to break, crack or deteriorate, as in the prior art. On the contrary, the stresses of part 2 are exerted against the surface of the plate 3, all around part 4, and are thus distributed over this whole surface, which supports them without any problem.
  • Figures 4 to 6 show a preferred embodiment of the invention.
  • the device comprises two plates, respectively 11 and 12, able to be made integral, respectively, with two parts of a prosthesis, by usual means, not shown, and an intermediate element 13, capable of being made integral, in a plurality of positions, with each of the elements 11 and 12.
  • Element 13 consists of a nut, comprising two cylindrical portions 14 and 15, with perpendicular axes, from each of which protrude, respectively, two portions 16 and 17, in the form of a trunk of pyramid with rectangular base, adjoining by their small base to the associated cylindrical portion, with their large base spaced from this cylindrical portion.

  • the elements 11 and 12 are hollowed out female parts intended to receive respectively, on the one hand, the male portions 14 and 16 of the element 13, on the other hand, the male portions 15 and 17 of this element.
  • the female part hollowed out in the element 11 comprises a cylindrical portion 18, of shape complementary to that of the part 14, and a groove 19, of substantially parallelepipedic section, directed parallel to the axis of the cylindrical part 14.
  • the transverse dimension of this groove 19, that is to say the dimension perpendicular to the direction of the axis of the cylindrical part 14, is greater than the corresponding dimension of the part 16 that it is intended to receive.
  • the longitudinal dimension of the groove 19, that is to say the dimension parallel to the axis of the cylindrical portion 14, is greater than the corresponding dimension of the part 16.
  • the female part hollowed out in the element 12 comprises a cylindrical portion 20, of shape complementary to that of the part 15, and a groove 21, of substantially parallel parallelepipedal section, directed parallel to the axis of the cylindrical part 15
  • the groove 21 has a length and a width greater than the corresponding dimensions of the portion 17, which allows the cylindrical portions 15 and 20 to be pivoted relative to each other and to adjust the position of the parts by translation. 17 and 21.
  • a double adjustment in position is therefore possible, in a particularly simple manner, at the level of each of the plates 11 and 12, which makes it possible to adjust the relative positions, angular and in translation, of the prosthesis parts integral with the plates 11 and 12.
  • the male parts can be carried by the elements 41 and 42 intended to be made integral with the parts of the prosthesis and the female parts can be formed in the intermediate element 43.
  • the male part of the element 41 comprises a cylindrical portion 44 from which protrudes a portion 45 in the form of a trunk of a pyramid, the large base of which is distant from the portion 44.
  • This portion 44 comes to cooperate with a female portion 46, in profile complementary to the element 43, while the portion 45 is housed in a groove 47 of this element 43, the sides of which are substantially parallel to the axis of the cylindrical part 44.
  • the transverse and longitudinal dimensions of the groove 47 are greater to the corresponding dimensions of the portion 45, so as to allow the portion 44 to pivot relative to the portion 46 and a sliding of the portion 45 relative to the groove 47.
  • the element 42 includes a male cylindrical portion 48, from which protrudes a portion 49 in the form of a trunk of a pyramid.
  • the axis of the portion 48 is perpendicular to that of the portion 44.
  • the portion 48 is housed in a female portion 50 of profile complementary to the element 43, while the portion 49 is housed in a groove 51, of which the sides are parallel to the axis of the part 48 and whose longitudinal and transverse dimensions are greater than those of the part 49, so as to offer the latter a double freedom of movement, allowing the portion 48 to be rotated by relative to the portion 50 and a translation of the portion 49 relative to the portion 51.
  • the element 61 may include a female cylindrical part 62 and a groove 63 with the sides parallel to the axis of the portion 62, intended respectively to receive a male cylindrical part 64 and a part in the form of a pyramid trunk 65 of the intermediate element 66, while, conversely, a female cylindrical part 67 with an axis perpendicular to that of the part 64 and a groove 68 of the intermediate element 66, with the sides substantially parallel to the axis of the cylindrical part 67, will respectively receive a male cylindrical part 69, of complementary profile, and a part 70 in the form of a truncated pyramid, making projection relative to a second element 71, intended to be rendered secured to one of the parts of the prosthesis.
